REV. 1.0.6
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 9 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 8 to be transmitted as received (via the
TxDS1Data9 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).

Bit 7 - Insert AIS Rx DS1 Channel 15
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 15 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data15 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 6 - Insert AIS Rx DS1 Channel 14
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 14 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data14 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 5 - Insert AIS Rx DS1 Channel 13
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 13 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data13 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 4 - Insert AIS Rx DS1 Channel 12
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 12 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data12 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all

Bit 3 - Insert AIS Tx DS1 Channel 15
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 15 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 15 to be transmitted as received (via the
TxDS1Data15 input pin).
Setting this bit-field to “1” configures the XRT72L13
